If you really want to disable this (note:  I don't recommend doing this,
but...), take a look at the /etc/pam.d/ configuration files for the service
you're wanting to use.  They probably have a line that says something to the
effect of "auth required /lib/pam/securetty_pam.so" or something vaguely
like that at or near the top.  Remove that line from the service you're
wanting to use, or add the tty you'll be coming in from to /etc/securetty
and you should be set.

What I'd do is come in as a normal user over ssh, and then su / sudo to root
(if you play games with pam config files, you can make su from members of
group wheel to root be passwordless), if I just had to have the script
running as root.
